How can I make the design by using collection view, please explain me. Here is the image of the design:
This is simply a UICollectionView with a UIPageControl below it.
You just need to design a UICollectionViewCell that looks like a card and use that in your collection view.
Have a look at [this Ray Wenderlich tutorial] to give you an idea how to use a UICollectionView. Of course you'll need a horizontal scrolling one, but that's easy configurable. Also read the iOS documentation.
You'll also need to scrolling to stop with one full card visible; read this.
Since you're new on StackOverflow you may not know this: On StackOverflow you're expected to first do your own research and try hard to get something working. Then when you have a detailed issue you can't figure out, you post that here. Please do so next time.

I'd really like to do something similar to Tinder's "pile of cards" interface, but with a UICollectionView.
I would assume that if you need the other cells to dynamically move given the cell you are interacting with, one would be in Edit Mode on a UICollectionView, but I'm not sure.
Please don't reply with specific Cocoapods that do this and "why don't I just use those?"; it goes beyond just that. I have all sorts of content, and this is just one of the layouts / presentation types I need. Sometimes it's a grid. A lot of the controller actions are the same; just the display and interaction is different.
That said, please DO refer me to any code that may already do this, that I could use as a starting point.
Otherwise, I would be grateful to know where I would get started. I'm thinking maybe one of those projects that re-creates Springboard with a collection view??
EDIT: I was looking for something like a card stack, but not like Tinder in that you can interact with the top card before swiping or letting it return. In the end what I was trying to accomplish was similar to the old iPod-style 'Cover Flow' view.
I'll try to answer my own post. I made a few incorrect assumptions. In the end it was a lot less complex than I thought.
To get a collection view whose layout isn't just 'static within a scrollview' but changes dynamically with the contentOffset property, you need to subclass UICollectionViewLayout and make sure first of all you return YES for - (BOOL)shouldInvalidateLayoutForBoundsChange:(CGRect)newBounds
from there, most of your heavy lifting will be done in the - (void)prepareLayout method.
I basically used the following tutorial as a starting point and kind of followed what they were trying to do (or just downloaded the final project and saw how they did it, and mimicked the same effect), but obviously had a different prepareLayout method:
Ray Wenderlich
Is what I'm trying to accomplish here even possible? I've been searching for hours for sample code and/or SO answers that demonstrate this simply enough to follow, but so far no luck.
Goal: implement something that looks roughly like this mock:
Yes, I know this is easy with a tableview, but the full design includes custom interactions, multiple columns, UIKit dynamics, and custom animations when adding/deleting cells, so UICollectionView is the better candidate. Until I can get this core layout to work, though, the rest of it is just a pipe dream.
So far I've started with a subclass of UICollectionViewCell that has a single label with constraints to all 4 sides of the content view. At which point I run into these issues:
It's unclear how I can calculate collectionViewContentSize() when the cells don't exist yet, esp. given that the majority of cells are actually offscreen most of the time!
If I just throw in an arbitrary content size (e.g., 320x1000), my views show up, but their heights don't adjust to the label content…I can't seem to read the cell height from within my UICollectionViewLayout subclass.
Seen or done anything like this? I'd include code, but after hours of futzing with it. I'm just looking for a clearer tutorial or sample code that fits this scenario.
There's a project you might want to look at. It's fairly involved and probably has a lot of code for situations that don't quite match yours, but does indeed create a chat view using a UICollectionView.
It can be found here:
https://github.com/jessesquires/JSQMessagesViewController
For item 1 - with regards to calculating collectionViewContentSize, I think you'll find you may not need to calculate that, at least as long as you're using a UICollectionViewFlowLayout subclass for the layout.
And for item 2 - rather than set a fixed 320x1000 take a look at the JSQMessagesCollectionViewFlowLayout.m for sizeItemAtIndexPath.
Sorry, this probably should have been a comment, but I lack the reputation to comment & so I made it an answer (doesn't that seem backwards? Ah well.)
I need to implement this screen and I wonder if anyone can help me with ideas to solve some scenarios, basically the screen will contain a parallax effect in the top image, the entire screen must be scrollable, the problem I am faced when designing this screen It is the way I see I need to have a scrollview and a tableview that generates me the trouble of having the scrolls in the same direction.
I've read several post here about the problem of having scroll inside scroll for example: Nested UITableView inside another nested table , and what I want are actually ideas that can help me implement the screen below.
I just need suggestions of good practice, no one needs to worry about post code unless some lib to help with the problem or something.
I appreciate any help.
I finally solved my problem, I implemented a solution based on ParallaxTableView and is-it-possible-to-add-uitableview-within-a-uitableviewcell
And here is my project : UITableViewHeader
The trick on that (DEPENDS IF YOU REALLY WANT THAT BEHAVIOR) is having the image on the table view header. there are plenty of tutorials on github with sample implementation also.
e.g that one
I want to implement a page control in my project so that every view can be accessed through swiping left or right. Every example I have looked at is to do with images, not views. I've been studying this and its of course images again. My application is a single view application. I'm not really sure what code snippets to give you so far, I don't think I do because I haven't done anything on this yet. If you need specifics, please comment and ask me, i'll be here all day.
Please help me!
Thanks.
The same idea should apply in the tutorial you cited. They're adding UIImageView to a UIScrollView. So in your case, instead of UIImageView just use UIView. Also you can think of the pageImages array as a data source about your views. For example, instead of an array of UIImage you can just have an array of some model object that helps you configure your view. However, keep in mind that the implementation in the tutorial for your case won't scale if you plan to have a lot of UIViews. That's because you want to effectively reuse views that aren't showing. When it gets to that point, you're better off implementing a UITableView that scrolls horizontally.
You can use UIPageViewController for paging effect. Check out this tutorial. It is written in obj-c but who cares. It will give you idea about using UIPageViewController.
Today I tried to implement a vertical tabbar for iPad. I checked a lot of questions on Stackoverflow and other sites but couldn't find the appropriate answer. Here are what I found:
https://github.com/futuresimple/FSVerticalTabBarController
https://github.com/nst/SEVerticalTabBar
https://github.com/NOUSguide/NGTabBarController
In my opinion, the third component is great. However, I guess I'll have to customize a lot before I can use to create this following UI:
So do you know any components/libraries that match my UI? It would be great if anyone can suggest me a correct one. Thanks.
Try to use FSVerticalTabBarController. I have used it and it is easy to modify...
You can try this component IIViewDeckController. Its very light weight.
Usually it will be used for Stackview, left Menu kind of UI.
But you can do a small trick like below to achieve your design above.
Steps:
The component have left, right, top, bottom and center stack of controllers.
Use a UITableView on your LeftViewController to design your above UI.
Each index will act as a container of OneViewController.
Clicking one cell of your tableview will place the appropriate ViewController in the center controller of IIViewDeckViewController.
Its very easy, I guess you will like it. Just take some time to go through their examples.
Hope it will be useful
I translated futuresimple/FSVerticalTabBarController into Swift 5.
My repo is https://github.com/coyingcat/VerticalTabBar
Apple's doc Implementing a Container View Controller is great also
